what is the circumference of a circular pond with a radius of 14 meters?

Answer 1

You are given the radius which is the distance from a side of the circle to its center. This length is 14.
The circumference of a circle is calculated by 2πr
2π14 2*14=28
So it can be either 28π or you can take the first digits of π which are 3.1415 and multiply that by 28
28*3.1415= 87.96
Therefore you end up with 2 different answers...
87.96 or 28π
